Etali, Primal Conqueror

Trample
When Etali, Primal Conqueror enters the battlefield, each player exiles cards from the
top of their library until they exile a nonland
card. You may cast any number of spells from among the nonland cards exiled this way
without paying their mana costs.
{9}{p/g}: Transform Etali. Activate only as a sorcery.
